WARIING APPARATUS.

Application filed February 27,1925.

Application `Serial No. 190,501,1iled September 10, 1917, by ,Howard D.Colman, (new Patent No. 1,544,055) discloses a warping lapparatus;comprising a warper .1 5 anda Creel, the latter being adapted tofsupport L- 'so-called cheeses, and being provided with: brakes to stopgjthe 1 rotatien 'Offflle eheesestupon :breakage or excessive Slackeningof; the yarn; the beam brake;ofthe-.Warp- 10 enbeing-simultaneouslyapplied toistopzthe beam. .Mechanism is provided vvhiohaetsautomatically immediately after stoppage of the warping apparatusltorelease the beam brake and place the cheese :brakes @in fsueh 5 positionthat they merely exerta light pressureaipon thejeheeses to preventcoasting thereof-While ,the Warper is being operated at lovv speed, or`Vincase the threads be Casin ally disturbed (thisi lightpressure `,ofthecheese brakes beinghereinafter termed the drag pressure) andsubsequently `to `remove the drag pressure andthus complete theresetting ofl the .blake mechanism.

clutch is manually Vthrown in by means `of the bell crank 119 andsubsequently auto` matically thrown out by the spring 102.

lVhen it is desired to stop the warper, the trip mechanism may be'manually operated to release the shaft 73 to the action of thebrake-applying springs 'Tl by pulling the before-inentioned hand lever,said lever operating through alink 125 (Fig. 1) as eX- plained in saidPeterson 8: Cummings patent. I have described the method of restartingthe warper after a stoppage due to a broken or slack thread. Then thewarper is stopped for removal of a full beam and for replenishment oftlie creel, the mode of operation preparatory to restart-ing is somewhatdifferent, as will now be explained. c

When the warper stops through the action of the warp'er clock (notshown), the'be'am brake is released and the creel brake mechanism movedto the drag position, as previ ously described. The operative thendiscern nects Vthe clutch on the rwai-per `as described in Petersonapplication Serial No. 706,834 filed April 16, 1924. She then pulls thebefore-mentioned hand lever, thus causing the resetting mechanism toremove the drag pressure from the cheeses and return to high speedoperating position. The warper how-v to operate at slow speed, and assoon as thethreads are under tension the operative pulls the hereinbefore-mentioned hand lever, thus (through the action of thelink 125)releas ing the shaft- 7 3 to the action of the spring means 74, wherebythe beam brake and the creel brakes are applied. Immediately thereafterthe operative pushes the hand lever and thus exerts pressure through thelink 118 upon the bell crank 119 to force the bell crank 119 against thestop 126, as shown in Fig. 7, thereby straightening the toggle 119a and120 slightly past dead center. The clutch is thus thrown out and lockedout of action, the throwing out occurring before the resetting cam hasturned more than a negligible' distance. By reference to Fig. T', itwill be understood that the locking put of the clutch causes compressionof the spring 991. The apparatus is now at rest, with the beam brake andcreel brakes set. The threads may now .be severed, and the beam removed.

lf when the warper is running it isnecessary or desirable to stop thewarper and leave the brakes on the cheeses, the operative pulls thebefore-mentioned hand lever and thus releases the brakeapplying springsil to action, 'thereby promptly stoppingvthe warper. sfsoo'n as thewarperhasstopped, the operative pushes onthc handl leverv and therebytlirows'out the clutch Iand locksit out of action, thus preventingthebrakeresetting mechanism from releasing-the benin brake and thecre'el brakes.
